Forces Flashcards
Equation for weight
Weight = mass x gravitational field strength
Equation for work done
Work done = force x distance
Equation for force
Force = spring constant x extension
Equation for moment of a force
Moment of a force = force x distance
Equation for pressure
Pressure = force normal to a surface/area of that surface
Equation for distance
Distance = speed x time
Both equations for acceleration
Acceleration = change in velocity/time taken
Acceleration = final velocity - initial velocity/time taken
Equation for resultant force
Newtons second law
Resultant force = mass x acceleration
Equation for momentum
Momentum = mass x velocity
Equation for pressure
Pressure = height of column x density of liquid x gravitational field strength
Equation involving velocity, acceleration and distance
(Final velocity)2 - (initial velocity)2 = 2 x acceleration x distance
Equation for force
Force = change in momentum/time taken
